AUTOMATIC SEWER FLUSHER.

Application led .Tune 20, 1927. Serial No. 200,036.

My invention is in connection with an l and is open at the side 4, towhich is connected the spout 5. This spout has a bottom 1nautomaticsewer flusherand has to do with a flushing pan construction `and themanner of making same.

An object of my invention is the construction particularly of a flushingpan for use with anautomatic sewer flusher, in which the y pan is formedof sheet metal, this being cut out of a fiat blank, being foldedonvarious lines in order to form when riveted or soldered a water tightcan sufliciently reinforced for the purpose in hand.

Another object of my invention is the particular manner of folding thesheet metal to form a reinforced base or bottom for the pan.

The type of pan used in the flusher has rectangular open bodyy portionwhich is adapted tobe positioned directly under Va flushing column andto be filled with waterv discharging from said column. One side has aspout connected thereto, the spout being the full depth of the side, andhaving a lower surface gradually inclined upwardly. In making such apanI cut a piece of sheet metal so as to form the bottom, the back andtwosides of the body portion, and have an elonf gated strip which, whenfolded, forms a reinforcement for the base or bottom and also the spout.The two sides of the spoutpfold upwardly and form the sidesof the spout.A pair of straps formingan integral part of the sheet metal strip arecarried up from the lower part ofthe spout over the upper edge of theside walls, thereby bracing the spout. The top of the spout is coveredby an additional cover plate.

My invention will be more readily understood from the followingdescription and drawings, in Vwhich y Figure 1 is an elevation of `asewer flusher with my pan installed therein, the manhole and well beingshown in section.

Figure 2 is a limgitut'linal section `on the line 2-2 of Fig. 3. n

Figure 3 is a plan view of the pan taken in the direction of the arrow 3of Fig. 2. f

Figure 4 is a plan of a blank cnt to shape and showingl the foldinglines fory forming the major part of the pan. f

Figure 5 is a longitudinal section showing the pan partly folded,illustrating onel step in the operation of making.

The main details of the pan are substantially as follows, havingreference particuof ille pan ner of folding.

numeral 17, and an end strip The panlias a base 1, a back 2, side walls3,

clined plate 6 and opposite sides 7. An extra cover plate 8 covers themajor part of the spout leaving a discharge orifice 9.

The manner of making the pan lis substan- 'tially as follows, referringparticularly to Figs. 4 and 5, in which:

A fiat base of sheet metal is illustrated cut to shape and having linesshowing the man- The sheet has a center'portion I which forms the base 1the back wall 2, the side walls 3, these parts being so designated onFig. 4 of the drawing. Line 10 indicating a bend shows the line onwhichthe back is bent upwardly with reference to the base or bottom, andthe lines11 the bending lines for the sides with reference to thebottom.A A tongue portion 12 extends from the base or botto'mfl and hastwo straps 13 cut, thel straps being beside the side walls 3, and whenfolded upwardly occupying the position indicated in igs. 1 and 2, with'the free ends 14 `of the straps bent over the inside ofthe side walls.

v The dotted Iine15indicates a bending line toy give the incline for thebottom of the spout and the line 16 a reverse'fold, these beingindicatedin Fig. 5. Tlie'back wall 2 has side strips 17 which are bent over onthe line 18 to engage the sides of the pan as indicated the 19 is foldedinwardly at the top of the back.

The dotted line 20 indicates a reverse fold, as shown in Fig. 5, so thatwhen the pan is folded in shape and made up there is a portion 21v ofthe tongue 12 resting directly on the the bottoni and the reverselyfolded sec-V tion 22 of the tongue extending towards the spout, thebottom 6 of the spout being in-` clined upwardly as above mentioned, and

' being braced by the lower part 23 of the vstrap 13 and by the reversebent portion 24 of the 1 portion 21. The dotted line 25 indica-tes thefold of the bottom 6 of the spout adjacent the open end of the bodyportion of the pan. The

side walls 7 of the pan are foldedupwardly along the lines 26, thesesides having projecting ends 27 which fit on the outside of the sidewalls 3. After the pan is folded into the shape shown in Fig. 2, rivetsare inserted throughk the over-lapping parts and through in attachingthe folding parts lirinly in position and the over-lnppingI partelirinly to gethcr.

rlhe spout has longitudinal corrugations Ql Jior the purpose ofstrengtheningV and the cover 8 has downwardly extending side 'flanges 29which are folded or. etherwise se cured to the top of the side walls 7ol the spout. |This structure makes up the body portion ot the spout andwhen completed gives a water tight sinfucture reinforced on tlc lease orbottoni. and having reinforcing straps supporting 'the spout.

A plate secured "fr tl e oa-se of the pan,

Y' being; placed on top oit the o'verlalvaping parts il ad this hayini:an enlarged eye 35 in which. the pan opera rodi connects.

The plato 3d which is c iected with the enlarged eye 35 is rivetedthrough the double :folded tong-'ue 'l2' ha ing the parte 2l and 22.Thus the plate @le adn; to th sti fness of the tolded sections oli 'thelonclret.

rlhis rod extends iipwardly through the {ius-,hing cclunin 37, d bymeans oit a swivel rod connected to the rocking lever 39. This leiterhas a stein l() connected thereto, to which is attacliied a Valve hell1li, such parts being common to the type oi? iiusher illus tinted, thistlusher being; iliade snhstan tially in accordance with the niainfeatures of the patent to Harrie Ui. Burns, No. 1,256,656, issuedFebruary 19, i918.

e llhe manner ot operation of the lusher inay he recited as follows:

rEhe manhole is {ille-d with waterloy ya constant cl'iarging pipe whenthe water reaches the top o'i the flush ng; column it onernows .uit-oapen until the pan receives a suliicie. t L ...o to tilt saine, and inthe tilting' o'l' the pan the pan oper l rod 36 is drawn downwardly,thus rocking the lever 39', which raises the hell valve lll, allowingthe manhole to tl sh into the well i3 and such water to wash down intothe sewer. lt will be seen, ilicrcliorc, that the pun is lonited in aninzicciisf-iihlo posi jon, requiring the taking out oli the licor andthm i icclianisin to renew or rei'iair the l n desirable to ha 'e a.sheet nicht pan si4 cie y rei "li-ccd in order to witlisteuul thejolting str ses of dumpin the water and returning to its normalposition. lt loind that a sheet metal pan, made in accordance with inyinvention, h as suficicntstrength 'for ordinary purposes and whenprogerly inane will withstand rus' 'for a. suniciently long` time, thuseffecting economy in construction maintenance over the present practiceusing other types of pans.
